 Abstract

Previously, patients with hemophilia faced regular blood transfusion as the only means of treatment. This has often resulted to the wide spread of HCV infection  in this population leading to the infection of up to 95% of them. Eventually, the complications of HCV or HCV associated problems results to more mortality than bleeding problems.

Aims

Assessment of effectivity and safety of HCV treatment in people with bleeding problems.

Material and methods

This study was conducted at the hepatology unit of the Moscow Regional Scientific Research and Clinical Institute named after M.F. Vladimir. A total of 32 patients diagnosed hepatitis C with co-morbidity of hemophilia A, B or Willebrand disease? Of which thirty were men and two women. Average age at the onset of treatment was 38years. Exclusion criteria were presence of HIV and other liver diseases.

32 (82.5%) of the patients had liver fibrosis stage 0 to 3 of the METAVIR scale and four had liver cirrhosis. All the patients were treatment naïve.

We had two groups who received different treatment line for a duration of 12 weeks. The first group (n=5) consisted of 2 patients diagnosed with genotype  1, 2 with genotype 3 and 1 with genotype 1b. All of them received a combination of lamda interferons, daclatasvir and ribavirin according to body mass. The second group consisted of 27 patients diagnosed with genotype 1b and all of the received Viekira Pak for 12 weeks.

Results

All the patients in the first group treated with interferon lamda, ribavirin and daclatasvir attained sustained virological response and 96.2% of the second group who received Viekira Pak attained  sustained virological response. Mutation in the RAS: Y93H was identified in one patient of the second group. The most common side effect identified was fatigue in about 60% of the first group and 15% of the second group. However, during treatment there was slight elevation of transaminase AST, ALT and leucopenia in the first group. But the trasaminase normalized soon after treatment. Throughout the treatment course, no episodes of severe bleeding were observed. No correction was of hemophilia treatment was required.

Conclusion

The treatment of HCV in hemophiliacs is safe and effective, but direct acting antiviral (DDAs)  drugs are preferred over interferons containing combinations. In spite of the intensifying patterns of COVID-19, no medications are approved to have noteworthy adequacy in clinical treatment of COVID-19 patients in huge scope considers. Angiotensin-changing over catalyst 2 (ACE2), which is a point by the infection. The recognition of ACE2 by the S protein of the infection allows the attack of the coronavirus into the human dissemination framework.

Single-strand RNA (22–26 kilobases) infections, for example, the coronavirus family replicate the infection genomes by gaining by have cells. For example, after coronavirus draws close to the ribosome of the epithelial cells or other host cells, it uses the ribosome of the host cell to recreate polyproteins. The replication and following strategies of antecedent polyproteins can emerge in the epithelial cells.

 

Contrasted and chloroquine, hydroxychloroquine has a hydroxyl gathering, which makes it less harmful while keeping up comparative movement. One instrument of activity of chloroquine and hydroxychloroquine is focusing on lysosome which might be helpful to control unite versus-have malady in people. With the gathering of chloroquine in lysosomes, the pH of lysosomes is altogether changed and the movement of proteases in lysosomes is straightforwardly influenced, in this manner influencing the debasement of proteins and glycosaminoglycan. Chloroquine can restrain the passage of SARS-CoV-2 and forestall infection cell combination by meddling with glycosylation of ACE2 receptor and its authoritative with spike protein, proposing that chloroquine treatment may be increasingly compelling in the beginning phase of disease, before COVID-19 decreases ACE2 articulation and action. Hydroxychloroquine has calming impact on Th17-related cytokines (IL-6, IL-17, and IL-22) in sound people, and foundational lupus erythematosus (SLE) and rheumatoid joint inflammation (RA) patients. There is some proof that chloroquine and hydroxychloroquine can lessen cytokine storm. As indicated by one examination, the fundamental driver of death of COVID-19 patients is identified with the activating of the cytokine storm, which added to intense respiratory misery. It has been accounted for that hydroxychloroquine is compelling in hindering SARS-CoV-2 contamination in vitro. Zinc restrains SARS-CoV and retrovirus RNA polymerase movement in vitro and zinc ionophores obstruct the replication of these infections in cell culture [43]. There is additionally proof that zinc upgrades chloroquine intracellular take-up [44]. All things considered, joining zinc with chloroquine or hydroxychloroquine is interesting and is as of now under scrutiny. By and large, progressively clinical preliminaries are in progress to assess the security and adequacy of hydroxychloroquine as a prophylactic and treatment for COVID-19. After the coronavirus polyproteins are shown, two compounds, coronavirus primary proteinase (3CLpro) and the papain-like protease (PLpro) are accepted to be engaged with cutting the polyproteins into littler items utilized for recreating new infections. So as to create the girl RNA genome, the coronavirus shows a RNA-subordinate RNA polymerase (RdRp), which is a significant replicase that catalyzes the blend of an integral RNA strand utilizing the infection RNA. CoVs assemble close to intracellular layers inside the Endoplasmic reticulum-Golgi transitional compartment (or ERGIC) after contamination. Remdesivir is viewed as the most encouraging antiviral specialist; it works by hindering the action of RNA-subordinate RNA polymerase (RdRp). A huge scope study researching the clinical adequacy of remdesivir (200 mg on day 1, trailed by 100 mg once day by day) is on-going. The other astounding enemy of flu RdRp inhibitor favipiravir is likewise being clinically assessed for its adequacy in COVID-19 patients. The protease inhibitor lopinavir/ritonavir (LPV/RTV) alone isn't appeared to give preferred antiviral adequacy over standard consideration. Be that as it may, the routine of LPV/RTV in addition to ribavirin was demonstrated to be successful against SARS-CoV in vitro. Another promising option is hydroxychloroquine (200 mg threefold day by day) in addition to azithromycin (500 mg on day 1, trailed by 250 mg once every day on day 2–5), which indicated incredible clinical viability on Chinese COVID-19 patients and hostile to SARS-CoV-2 intensity in vitro. The jobs of teicoplanin (which represses the viral genome introduction in cytoplasm) and monoclonal and polyclonal antibodies in the treatment of SARS-CoV-2 are under scrutiny. Keeping away from the solution of non-steroidal mitigating drugs, angiotensin changing over chemical inhibitors, or angiotensin II type I receptor blockers is exhorted for COVID-19 patients.
